With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the ...
Life Sciences |Computer scientists at the University of Washington have used Android, the open-source mobile operating system championed by Google, to turn a cell phone into a versatile data-collection device....
Information Technology |The mantis shrimps in the study are found on the Great Barrier Reef in Australia and have the most complex vision systems known to science. They can see in twelve colours (humans see in only three) an...
Physics and Astronomy |But does she really? Can dogs understand deception? Mark Petter, a Dalhousie *University PhD student in clinical psychology, wanted to find out whether dogs could recognize if humans had the i...
Studies and Analyses |These animals and others also can repair damaged heart tissue and injured structures in the eye. In contrast, humans have only rudimentary regenerative abilities, so scientists hoping eventually to de...
Life Sciences |The discovery could contribute to better understanding of human diseases that affect the retina, including age-related macular degeneration, the leading cause of blindness in Americans over 50. That...
Life Sciences |"By showing the locations of people within a building during hostage situations, fires or other emergencies, radio tomography can help law enforcement and emergency responders to know where they ...
Physics and Astronomy |Adults with shingles were about 30 percent more likely to have a stroke during a one-year follow-up than adults without shingles, in a study reported in Stroke: Journal of the American Heart Associati...
Studies and Analyses |The brain’s neural mechanisms keep straight which color belongs to what object, so one doesn’t mistakenly see a blue flamingo in a pink lake. But what happens when a color loses the object to which it...
Life Sciences |These basic functions often work about the same in people as they do in “model” animals. But if you want to study more sophisticated cognitive processes such as humans’ ability to learn language from ...
Life Sciences |Writing online Wednesday in the journal Nature, scientists cast a rosy light on the potential for gene therapy to treat adult vision disorders involving cone cells — the most important cells for visio...
Life Sciences |Among the participants in the shipboard workshop (hosted by Fisheries and Oceans Canada) was Ron Kwok of NASA's Jet Propulsion Laboratory in Pasadena, Calif. Kwok has long provided checkups on th...
Earth Sciences |CSIRO Mathematical and Information Sciences image analyst Leanne Bischof helped develop the Gemmological Digital Analyser (GDA).Ms Bischof said that opals have a unique range of colour charact...
Information Technology |Fish and some amphibians possess a unique sensory capability in the so-called lateral-line system. It allows them, in effect, to "touch" objects in their surroundings without direct physical...
Physics and Astronomy |With more than 1,500 eyes, not much escapes the fruit fly's sight. Now, a new research report in the journal GENETICS, describes how researchers from the United States and Ireland used those eyes...
